In a release issued Wednesday, the Denison Police Department said that skimmers are regularly found around Grayson County.. The department also warned area residents about what to look for when visiting local gas stations and other places.
“Credit/Debit Card skimming devices have been regularly found in Grayson County and across the nation but usually the gas stations with the least secure hardware to take your payment at the pump are being targeted,“ the release said.
How can you tell if the pump has encrypted payment hardware making it less likely your payment information will be stolen, the release asked.
“If the pump has a horizontal card reader and the keys on the pad are raised,” it said. “What kind of pump are you most likely to have your credit/debit card information from? Vertical card reader and flat membrane key pad.“
The Herald Democrat previously released a list of five things to know about skimmers. Here is a reprint of that information that was provided by Denison Police Lt. Mike Eppler.
1. Where are skimmers found?
Card-skimmers are typically used at high-traffic businesses and locations that accept credit and debit cards. They’re most often found at gas pumps, ATMs and restaurants.
2. How do they work?
Skimmers record and save a variety of data including card numbers, PIN numbers, zip codes and cardholder information.
The devices can be attached externally to real card slots and are frequently made to match the look of the machine on which they’re used. But when criminals want to keep skimmers out of sight, they may also install them inside of pump card-reading machines.
After leaving the skimmers for some time, criminals return to remove them or download the information recorded. This can be done manually or even wirelessly with a smart phone and Bluetooth connection.
Portable or hand-held skimmers are less common, but use the same wireless technology.
3. What happens to victims’ information?
Card numbers and other information stolen by skimmers are typically used to make unauthorized purchases, especially online.
But criminals can profit even further by selling stolen card numbers to black-market buyers around the world, making the activity more difficult to trace and track. Cardholder information may also be used in part to steal an individual’s identity.
4. Warning signs
Police often recommend that card users visually check any machine they intend to use. External skimmers can be detected and dislodged by simply wiggling the housing around the card slot. Many gas stations will also use security tape or seals on their pumps to show evidence of internal tampering.
If a seal appears to be cut or damaged, do not use the machine.
Suspicious charges, transfers and withdrawals may also point to card-skimming activity, so cardholders are advised to regularly monitor their accounts and transaction histories.
5. Tips for victims
Those who believe they’ve been a victim of card-skimming or find devices are advised to let the the affected business know and contact their local police department. Potential victims should also notify their bank and card companies, and regularly monitor their accounts and transaction histories. A replacement should be sought for any compromised card.
